Abstract: A packaging foil is continuously withdrawn from a supply. The foil is folded around the products to be packaged. Cut-off lengths of closing profile sections are inserted with a feed unit between the two longitudinal edges of the foil. In a sealing station, the two longitudinal edges of the foil are sealed together and the foil is then sealed onto the closing profile sections. In another sealing station, transverse sealing seams are formed between the free ends of successive closing profile sections and the tube is cut approximately in the center of the transverse seams. A high packaging output is achieved as a result of the continuous withdrawal of the foil.
